Answer
$123,155$
Work Step by Step
The formulas for horizontal component $x$ and vertical component $y$ of a vector $\textbf{v}$ having magnitude $|\textbf{v}|$ and direction angle $\theta$ are:
$x=|\textbf{v}|\cos\theta$ and $y=|\textbf{v}|\sin\theta$
Substituting the values of $|\textbf{v}|=198$ and $\theta=128.5^{\circ}$ in the formulas above,
$x=198\cos128.5^{\circ}\approx-123$
$y=198\sin128.5^{\circ}\approx155$
Therefore, $|\textbf{v}|=\langle -123,155 \rangle$
Since the question requires magnitudes of horizontal and vertical components, the magnitude of horizontal component is $123$ and the magnitude of vertical component is $155$.
